The high concentration of niacinamide (vitamin B3) works to brighten skin tone and improve the appearance of enlarged pores, while the zinc helps to balance visible aspects of sebum activity. This formulation is perfect for those looking to target dark spots, uneven skin tone, and overall skin texture for a clearer, more radiant complexion.
